Question

大家好我有一个简单的XML文档：

<iPhone>
 <enAttente>
  <UDID>value</UDID>
  <adresse>value</adresse>
 </enAttente>
 <enAttente>
  <UDID>value</UDID>
  <adresse>value</adresse>
 </enAttente>
</iPhone>

我想删除＆lt; enAttente＆gt; ，其中＆lt; adresse＆gt; = myValue 这就是我所做的：

$doc = new DOMDocument;   
$doc->load('./folder/myFile.xml');  
if ($doc)
{
    $domNodeList = $doc->getElementsByTagname('enAttente');

    for ($i = 0; $i < count($array); $i++)
    {
        foreach ($domNodeList as $domElement ) {
         $authors = $domElement->getElementsByTagName( "adresse" );
         $author = $authors->item(0)->nodeValue;

         if ($author == "myValue")
         {
             echo"Founded ! Delete this node ! -- ";
             // HOW CAN I DELETE this <enAttente> !!
         }
        }
    }

    $doc->saveXML();      
}

当我找到要删除的元素时，有人可以删除元素吗？非常感谢你！

Answer 1

在我看来，你需要

$domElement->parentNode->removeChild($domElement);

Answer 2

好的，这里有一些工作代码：

<?php
$file = './folder/myFile.xml';
$doc = new DOMDocument;   
$doc->load($file);  
if ($doc)
{
    $domNodeList = $doc->getElementsByTagname('enAttente');

    foreach ($domNodeList as $domElement ) {
        $authors = $domElement->getElementsByTagName('adresse');
        $firstNode = $authors->item(0);

        $author = $firstNode->nodeValue;
        if ($author == "myValue")
        {
            echo "Founded ! Delete this node ! -- ";
            $doc->documentElement->removeChild($domElement);
        }
    }

    $doc->save($file);      
}

使用DOMDocument删除php中的XML元素
